To 4-{3-[1-(1H-Benzoimidazole-2-carbonyl)-azetidin-3-yl]-pyrazin-2-yl}-3,6-dihydro-2H-pyridine-1-carboxylic acid tert-butyl ester (217 mg, 0.47 mmol) was added 4 M HCl in MeOH (100 mL). The solution was stirred at RT for 2 h. The solvent was removed under reduced pressure to give (1H-benzoimidazol-2-yl)-{3-[3-(1,2,3,6-tetrahydro-pyridin-4-yl)-pyrazin-2-yl]-azetidin-1-yl}-methanone hydrochloride (187 mg, 0.47 mmol, yield 100%). ESI-MS (M+1): 361 calc. for C20H20N6O 360.
